jQuery animate() 和缓动类型

jQuery animate() and easing type

我有这个:

$('h1').animate({
    //stuff to be changed,
}, {
    duration: 1000, 
    queue: false
})

改成这样不接受:

{
    duration: 1000, 
    queue: false, 
    easing: easeOutBounce
}

当以字符串形式提供 easing 时,出现此错误:

Uncaught TypeError: n.easing[this.easing] is not a function

我应该如何放置缓动类型?

缓动应该是一个字符串,像这样:

{
    duration: 1000,
    queue: false,
    easing: 'easeOutBounce'
}

关于 .animate() 状态的 API 文档:

easing (default: swing)

Type: String

A string indicating which easing function to use for the transition.
